Hello,
so I cannot get to the GUI when I login. I get sent to the CLI where I login with firefly:firefly and I cannot get to the desktop. It worked yesterday then I had to start over and re-imaged a new SD card. Any help would be greatly appreciated.

I got that too.
Your device may be overheating. Check your heatsink and or remove the enclosure when you first install the image.
Also, before you re-flash your image, you can try the command # sudo e2fsck -y /dev/ where, is the name of your block device.

Mine was : firefly@firefly:~$ sudo e2fsck -y /dev/mmcblk0p5
the sudo fdisk -l command should be able to find your block device if the error message doesn't tell you, or you can list the boot messages $ sudo cat /var/log/syslog

That seemed to fix my corruption. ext4 doesn't have any crc checking for files. I need to try convert over to the BTRFS file system but, i'm still learning. Not sure how far I will get.
Just try the above first.

If none of that helps, re-image the flash unit and try again from the start. Just make sure the CPU is not overheating when booting and the power supply is allowing enough power.
